I just made a swap today for a 97 F350 CC Dually 5 speed. When I looked over the truck I let it run and idle for several minutes and then we drove it for several minutes. The gentleman drove about an hour to meet me. Well we traded and we headed back home which was about 45 miles or so. Well the truck ran great. We stopped at a buddies house for about 20-30 minutes. We went to leave I started it and it idled for about 1 minute and began skipping and the check engine light came on. This last for about 20-30 seconds and light went off and ran fine until a few miles up the road it did it again and then ran fine. Removed top cover and found what I think is the oil pressure switch for the injectors leaking up through switch into plug. I cleaned plug and drove truck to the store and the truck only seems to do this in the first few minutes of running after it sits. Once you get going and get on your way it runs fine. I will go get the sensor tomorrow because it needs replacing either way. Please help I am not very experinced with diesels. Oh and of course the guy I traded with has never had this problem. Thanks in advance for the help.

first if you can scan it do that! adn see what it says.
I think that your problem is under valve cover gaskets, which will throw a code like 0236? cyl? short, etc, which means the wiring harness is toast.
simple test, open the oil cap and smell it , if its burnt smelling then its wirign harness.
no worries it happens.

That might be the ICP. Or is the nut on the IPR tight. If you don't know the abbreviations then search the site You'll learn them sooner or later..LOL If you mess with these trucks much!

Thanks guy for the info. All though Im not very familiar with these engines Im not completely ignorant to them. We owned a shop for several years and I wrote service at a Ford dealership for about a year. The sensor thats leaking is the ICP which I will have tomorrow. After talking to my old diesel tech he told me to unplug the injector harness at the valve cover. Well when I pulled the passenger rear apart it was covered in oil and missing the end pins. So looks like I need ICP sensor, 1 harness for under the valve cover and luckily for me they have repair connecters for the harness. Hopefully tomorrow evening I cant get all this done and see how it runs. Thanks to good friends and not burning bridges Im only gonna be out about 40 bucks if this takes care of it.

Alright appears the problem is solved. Installed new ICP sensor and replaced all injector harnesses and two pigtails on the engine harness. Knock on wood it seems to be all better now. Now hopefully I can start enjoying my never veture into owning a diesel.
